2015/01 3.General Information 7
3. General Information
3.1. DESCRIPTION
HYGINOX SE is a range of close-coupled centrifugal pumps with hygienic design, suitable for use in the dairy,
beverage, and food industry in general.
This single-stage horizontal pump has a circular casing with axial suction and tangential discharge. The main pump
components are: pump casing, impeller, cover, lantern and a shaft which is rigidly coupled to the motor shaft.
The standard IEC motor of type IM B34 is protected by a stainless steel shroud and provided with height adjustable
stainless steel legs.
3.2. APPLICATION
As a general rule, HYGINOX SE pumps in their standard version are used in the food industry mainly to transfer
liquids.
For each type of the pump, the hydraulic performance is given by the choice of impeller diameters and speeds. The
characteristic curves also show the power and NPSH requirements. The intended use of the pump is defined by its
characteristic curve and operating limits provided in the Technical Specifications section.
Misuse of the pump or its use beyond the operating limits may be dangerous or cause permanent damage
to the equipment.

4. Installation
4.1. RECEPTION OF THE PUMP
INOXPA will not be liable for any deterioration of the material due to transport or unpacking. Visually
check that the packaging has not been damaged.
The following documentation is included with the pump:
·Shipping documents.
·Instructions and Servicing manual for the pump.
·Instructions and Servicing manual for the motor (*).
·(*) If the pump has been supplied with a motor from INOXPA.
Unpack the pump and check the following:
·The suction and discharge connections on the pump,
removing any remaining packaging material.
·
Check that the pump and motor have not suffered any
damage.
·
If not in good material condition and/or if not all the parts
are included, the shipping carrier should submit a report
as soon as possible.
4.1.1. Identification of the pump
Each pump has a nameplate with the basic data required to identify the model.

2015/01 4.Installation 9
4.2. TRANSPORT AND STORAGE
The
HYGINOX SE pumps are often too heavy to be stored manually.
Lift the pump as indicated below:
4.3. LOCATION
Place the pump in a position that allows enough space around it to provide access to the pump as well as to the
motor. (Refer to Section 8
. Technical Specifications for dimensions and weights.
Place the pump on a flat and level surface.
Install the pump so that it can be properly ventilated.
If the pump is installed outdoors, it must be sheltered under a roof. Its location must allow for easy access
during any inspection or maintenance tasks.
4.4. PIPES
·As a general rule, install the suction and discharge lines in straight sections, with the minimum possible number of
elbows and fittings in order to reduce any pressure losses that may be caused by friction.
·Make sure that the pump’s ports are properly aligned with the pipework and have a diameter similar to that of the
pump connections.
·Place the pump as close as possible to the suction tank and whenever possible below the liquid level, or even below
the tank level in order to achieve the largest possible static head for suction.
·Install support brackets for the lines as close as possible to the pump's suction and discharge ports.
4.4.1. Shut-off valves
The pump may be isolated for maintenance. To accomplish this, shut-off valves must be installed and connected to
the pump's suction and discharge connections.
These valves must ALWAYS be open during operation of the pump.
ATTENTION!
Always remove the motor
shroud before hoisting.
01.011.32.0003

10 4.Installation 2015/01
4.5. ELECTRICAL INSTALLATION
Only qualified personnel can connect the electric motors.
Take the necessary measures to prevent damage to cables and connections.
Electrical equipment, terminals and components of the control systems may still carry current when they
are disconnected. Contacting them may impose a hazard to operators or cause irreparable material
damage.
Prior to handling the pump, make sure that the electrical panel is disconnected.
·Connect the motor in accordance with the instructions supplied by the motor manufacturer.
·Check the direction of rotation.
Start and stop the pump motor momentarily. Make sure, looking at the pump from behind, that the motor fan
rotates in a clockwise direction.
A
LWAYS check the direction of rotation of the motor with liquid inside the pump.
ATTENTION!
See indicator label on the pump.
Seen from the rear of
the motor.

2015/01 5.Starting the pump 11
5. Starting the pump
Prior to starting the pump, carefully read the instructions in Section 4.
49H Installation .
5.1. START-UP
Carefully read Section 8.
H
Technical Specifications . INOXPA will not be liable for improper use of the
equipment.
NEVER touch the pump or the lines if hot liquids are being pumped.
5.1.1. Checks before starting the pump
·Completely open the shut-off valves on the suction and discharge lines.
·If liquid does not flow towards the pump, fill it with the liquid to be pumped.
The pump must never turn dry.
·Check that the direction of rotation of the motor is correct.
5.1.2. Checks when starting the pump
·Check that the pump is not making any strange noises.
·Check if the absolute inlet pressure is sufficient to prevent cavitation in the pump. Check the curve to obtain the
minimum required pressure above the vapour pressure (NPSHr).
·Control the discharge pressure.
·Check for leaks in the sealing areas.
A shut
-off valve shall not be used to regulate the flow in the suction line. All shut-
off valves must be fully
open during operation.
Control the motor consumption to prevent an electrical overload.
Reduce the flow rate and the electrical power
consumed by the motor:
·
by regulating the pump's discharge flow.
·
by decreasing the motor speed.
Use special protection when the
sound pressure in the operation area exceeds 80 dB(A).

7. Maintenance
7.1. GENERAL CONSIDERATIONS
This pump, just like any other machine, requires maintenance. The instructions contained in this manual cover the
identification and replacement of spare parts. The instructions are aimed at maintenance personnel and those
responsible for the supply of spare parts.
Carefully read Chapter 8.
H
Technical Specifications .
All replaced material should be duly disposed of/recycled according to the directives in force in each area.
ALWAYS disconnect the pump before beginning any maintenance work.
7.1.1. Check the mechanical seal
Periodically check that there are no leaks around the shaft. If leakage is detected through the mechanical seal, replace
it following the instructions in the section Assembly and Disassembly.
7.2. STORAGE
Before storing the pump it should be completely drained. Prevent as far as possible exposing the parts to excessively
humid environments.
7.3. CLEANING
The use of aggressive cleaning products such as caustic soda and nitric acid may burn the skin.
Use rubber gloves during the cleaning process.
Always use protective goggles.
7.3.1. CIP (Clean-in-Place) cleaning
If the pump is installed in a system with a CIP process, its removal will not be required. If an automatic
cleaning process is not available, disassemble the pump as indicated in the section
Assembly and Disassembly .
Cleaning solutions for CIP processes.
Only use clear water (chlorine-free) to mix with the cleaning agents:
a) Alkaline solution: 1% by weight of caustic soda (NaOH) at 70ºC (150ºF)
1 kg NaOH + 100 litres of water = cleaning solution
or
2.2 litres of 33% NaOH + 100 litres of water = cleaning solution
b) Acid solution: 0.5% by weight of nitric acid (HNO3) at 70ºC (150ºF)
0.7 litres of 53% HNO3+ 100 litres of water = cleaning solution

14 7.Maintenance 2015/01
Check the concentration of the cleaning solutions; incorrect concentrations may lead to deterioration of
the pump seals.
To remove any traces of cleaning products, ALWAYS perform a final rinse with clean water at the end of the cleaning
process.
7.3.2. SIP (Sterilization-in-Place) cleaning
Sterilization with steam is applied to all equipment including the pump.
Do NOT use the equipment during the steam sterilization process.
The parts/materials will not be damaged if
the indications specified in this manual are observed.
Make sure that no cold liquid enters the system until the temperature of the pump is lower than 60°C
(140°F).
The pump generates an important pressure loss through the sterilization process. We recommend the
use of a branch circuit with a discharge valve to ensure that steam / superheated water sterilizes the
integrity of the circuit.
Maximum conditions during the SIP process with steam or overheated water
a) Max. temperature: 140°C / 284°F
b) Max. time: 30 min.
c) Cooling: Sterile air or inert gas
d) Materials: EPDM
